Charge-distribution modulation of copper ferrite spinel-type catalysts for highly efficient Hg-0 oxidation
Hg-0 catalytic oxidation is an attractive approach to reduce mercury emissions from industrial activities. How-ever, the rational design of highly active catalysts remains a significant challenge. Herein, the charge distribution modulation strategy was proposed to design novel catalysts: copper ferrite spinel-type catalysts were developed by introducing Cu2+ cations into octahedral sites to form electron-transfer environment. The synthesized catalysts with spinel-type stoichiometry showed superior catalytic performance, and achieved > 90 % Hg-0 oxidation efficiency in a wide operation temperature window of 150-300 degrees C. The superior catalytic performance was closely associated with the mobile-electron environment of copper ferrite. Hg-0 oxidation by HCl over copper ferrite followed the Eley-Rideal mechanism, in which physically adsorbed Hg-0 reacted with active chlorine species. Density functional theory calculations revealed that octahedral Cu atom is the most active site of Hg-0 adsorption on copper ferrite surface. Both direct oxidation pathway (Hg* -> HgCl2*) and HgCl-mediated oxidation pathway (Hg* -> HgCl* -> HgCl2*) played important role in Hg-0 oxidation over copper ferrite. HgCl2* formation was identified as the rate-limiting step of Hg-0 oxidation. This work would provide a new perspective for the development of admirable catalysts with outstanding Hg-0 oxidation performance.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 14347-78-5 is helpful to your research. Category: copper-catalyst.
